A QEMU migration stream is a sequence of 'sections'.
There are 4 (main) types of section:
FULL: The entire contents of a device - that's most cases
START: The start of a devices data that we're going to save
split across multiple sections
PART: More of a device previously that we had already sent a
START for
END: The end of a device that we sent a START for
Most devices we can send in one go (FULL); but some devices
are 'iterative' and need to be broken up into chunks - RAM is
the most common example because it's a lot of data that changes as
we're saving it.
